I think the thing I'm trying to get at here is that winrar support should already be added despite the fact that pirates use winrar to distribute their files.

Why? Because it's convenient for the user.

Even if Windows 7 doesn't include winrar, what's going to stop the pirates from downloading it anyway? Hell, what's stopping them from pirating winrar pro?

It's just a few minutes annoyance for a pirate to download it, quite a few minutes annoyance for people who don't know what WinRaR is and receive a .rar file from a friend.

I don't advocate piracy and I don't think including winrar in W7 would increase it either. It's just like you people fighting against DRM because you say "It doesn't matter the pirates will pirate it anyway it will make it convenient for us if developers didn't include DRM."

Don't be hypocritical here people...

How the hell did you go from WinRAR to piracy?

The point is, WinRAR is a third-party compression and is not just free to MS to distribute in their OS. If they included support, there would be lawsuits. They will never add .rar support, because they would have to pay for the rights to use it.
